Although most online retailers carry the 'standard' Guerlains, department stores don't. The Perfumania chain stocks Vetiver (which is where I bought mine). I'm sure you can also find some at mall stands and the like and local fragance shops. For samples (online) you can either buy minis from sites like beautyencounter.com., or buy decants from theperfumedcourt.com. For the fragrances you mentioned, you may find the online retailers much cheaper than the Guerlain boutique at Bergdorfs, but for the more rare Guerlains that boutique in NYC and the others in Vegas, Miami, etc. are the only sources.
